0302.72.50.01 - Ictalurus spp.

This classification covers fresh or chilled catfish, specifically of the genus *Ictalurus*. This genus includes various species commonly known as North American bullheads and channel catfish. The primary characteristic for inclusion in this category is the species identification as belonging to the *Ictalurus* genus, differentiating it from other types of catfish and fish listed within the broader heading 0302.

Distinguishing this category from its siblings, 0302.72.50.04 specifically designates *Pangasius* species, often marketed as basa and tra. Therefore, any catfish not belonging to the *Ictalurus* genus, such as those from the *Pangasius* genus, would be classified under the sibling category. The category "Other" at this level would encompass any catfish species not explicitly defined by the preceding subheadings, though this specific *Ictalurus* classification captures a distinct group.

As this node represents a leaf category within the HTS structure, there are no further subcategories. Classification under 0302.72.50.01 is final based on the identification of fresh or chilled catfish belonging to the *Ictalurus* genus. Therefore, the key classification criterion is accurate species identification of the imported or exported product.
